Referring to fig. 2, fig. 2 is a flow chart illustrating a frequency domain resource allocation method according to an embodiment of the present application. It should be noted that, the frequency domain resource allocation method in the embodiment of the present application is executed by the terminal device. As shown in fig. 2, the method may include the steps of:

step 201, receiving indication information sent by a network device.

In the embodiment of the application, the terminal equipment receives the indication information sent by the network equipment, wherein the indication information is used for indicating the terminal equipment to determine the frequency domain resource occupied by the control resource set CORESET.

In some embodiments, the indication information is used to indicate that the frequency domain resource occupied by the CORESET is a continuous frequency domain resource unit.

In some embodiments, the indication information includes at least 1 bit, and each bit of the indication information is capable of indicating whether a corresponding set of frequency domain resource units is frequency domain resources occupied by the CORESET.

The frequency domain resource units may be resource blocks RB, physical resource blocks PRB (PhysicalResource Block), virtual resource blocks VRB (Virtual Resource Block), common resource blocks CRB (CommonResource Block), and the like.

Step 202, determining the frequency domain resources occupied by the control resource set CORESET according to the indication information, wherein the frequency domain resources occupied by the CORESET are continuous frequency domain resource units; or the frequency domain resource occupied by the CORESET is discontinuous at least two frequency domain resource unit groups, and the frequency domain resource unit groups are obtained by dividing a plurality of frequency domain resource units according to one of at least two granularities.

In the embodiment of the application, the terminal equipment can determine the frequency domain resource occupied by CORESET according to the indication information.

As an implementation manner of the embodiment of the present application, the frequency domain resource occupied by the CORESET is a continuous frequency domain resource unit.

In some embodiments, the terminal device may determine, according to the indication information, a starting position of the frequency domain resource occupied by the CORESET, and a size of the frequency domain resource occupied by the CORESET, so as to determine the frequency domain resource occupied by the CORESET.

In some embodiments, the terminal device may obtain a starting position of the frequency domain resource occupied by the CORESET specified in the protocol, and determine the size of the frequency domain resource occupied by the CORESET according to the indication information, so as to determine the frequency domain resource occupied by the CORESET.

In some embodiments, the terminal device may obtain a starting position of the frequency domain resource occupied by the CORESET specified in the protocol, determine a highest aggregation level and a time domain symbol number of the terminal device according to the indication information, further determine a size of the frequency domain resource occupied by the CORESET according to the highest aggregation level and the time domain symbol number of the terminal device, and further determine the frequency domain resource occupied by the CORESET.

In some embodiments, the size of the frequency domain resource occupied by the CORESET can also be determined according to the highest aggregation level of the terminal device, the number of PDCCH candidate channels supported by the highest aggregation level, and the number of time domain symbols.

Wherein, optionally, the size of the frequency domain resource may be matched with the bandwidth supported by the terminal device, so as to avoid resource waste. In the embodiment of the present application, the matching refers to that the size of the frequency domain resource is as close as possible to the length of the bandwidth supported by the terminal device.

It may be understood that, in the embodiment of the present application, the bandwidth supported by the terminal device may be a bandwidth (bandwidth), or may be a partial Bandwidth (BWP).

In the embodiment of the present application, the size (size) of the frequency domain resource may also be referred to as the length of the frequency domain resource, that is, the number of frequency domain resource units included in the frequency domain resource.

As another implementation manner of the embodiment of the present application, the frequency domain resource occupied by the CORESET is at least two discontinuous frequency domain resource unit groups, and the frequency domain resource unit groups are obtained by dividing a plurality of frequency domain resource units according to one of at least two granularities.

In some embodiments, the indication information includes at least 1 bit, the indication information can indicate a position of the at least one frequency domain resource unit group in a plurality of frequency domain resource units configured by the network device, and each bit of the indication information can indicate whether a corresponding group of frequency domain resource units is a frequency domain resource occupied by the CORESET.

In some embodiments, the granularity is determined based on at least one of: granularity indication information; the bandwidth supported by the terminal equipment; the number of bits of the indication information; the number of resource element groups REG (Resource Element Group) occupied by the control channel element CCE (Control Channel Element); the number of the time domain symbols configured by the network equipment can flexibly configure the allocation granularity according to actual conditions, so that the resource utilization rate is further improved, and the resource waste is avoided.

In some embodiments, in response to the existence of the remaining resource element group REGs that are not mapped to the control channel element CCE, releasing the remaining REGs can further improve the resource utilization rate, avoiding resource waste.

As described above, in the related art, the indication information indicates that the frequency domain resources occupied by the CORESET are discontinuous at least two frequency domain resource unit groups, the frequency domain resource unit group includes 6 frequency domain resource units, and the allocation granularity of the frequency domain resources of the CORESET is 6.

In some implementations of the embodiments of the present application, the discontinuous at least two frequency domain resource unit groups occupied by CORESET are obtained by dividing a plurality of frequency domain resource units according to one of at least two granularity, that is, the granularity of frequency domain resource allocation is changed.

In some implementations of the embodiments of the present application, the frequency domain resources occupied by the CORESET are consecutive frequency domain resource units, that is, the manner in which the frequency domain resources are allocated is changed.

In summary, receiving indication information sent by network equipment, and determining frequency domain resources occupied by a control resource set CORESET according to the indication information, wherein the frequency domain resources occupied by CORESET are continuous frequency domain resource units; or the frequency domain resources occupied by the CORESET are discontinuous at least two frequency domain resource unit groups, the frequency domain resource unit groups are obtained by dividing a plurality of frequency domain resource units according to one of at least two granularities, and the distribution mode of the frequency domain resources of the terminal equipment or the distribution granularity of the frequency domain resources can be flexibly configured, so that the terminal equipment can support higher aggregation level as much as possible, the transmission performance of a downlink channel is effectively improved, the coverage of the downlink channel is enhanced, the communication efficiency of the system is improved, the resource waste is effectively reduced, and the resource utilization rate is improved.

Referring to fig. 3, fig. 3 is a flow chart illustrating a frequency domain resource allocation method according to an embodiment of the present application. It should be noted that, the frequency domain resource allocation method in the embodiment of the present application is executed by the terminal device. As shown in fig. 3, the method may include the steps of:

step 301, receiving indication information sent by a network device.

In the embodiment of the present application, the indication information may be an RIV joint code, and the terminal device may determine, according to the RIV code, a starting position of a frequency domain resource allocated to the CORESET and a frequency domain resource length.

The RIV code is determined by the network device according to the starting position and the frequency domain resource length of the frequency domain resource allocated to the CORESET, and the terminal device can decode the RIV code after receiving the RIV code to determine the starting position and the length of the frequency domain resource allocated to the CORESET.

As an example, RIV encoding may be determined in the following manner.

If (L-1). Ltoreq.N/2|, RIV=N (L-1) +RB _START . Otherwise, riv=n (N-l+1) + (N-1-rbstart) & lt, where N represents the number of frequency domain resource units included in the bandwidth supported by the terminal device, L represents the size of the frequency domain resource, RB _START Representing the starting position of the frequency domain resource, the RIV representing the RIV code is a table of at least 1 bitThe values shown.

Step 302, determining a starting position of the frequency domain resource occupied by the control resource set CORESET and a size of the frequency domain resource occupied by the CORESET according to the indication information.

In the embodiment of the application, the terminal equipment can receive the RIV code sent by the network equipment and can determine the starting position of the frequency domain resource occupied by the control resource set CORESET and the size of the frequency domain resource occupied by the CORESET according to the RIV code.

In some embodiments, the terminal device may determine, by using a table look-up method, a starting position and a length of the frequency domain resource corresponding to the RIV value according to the RIV encoded value.

In some embodiments, the terminal device may also decode the RIV code by calculating, and determine the starting position and the length of the frequency domain resource corresponding to the RIV value.

As an example, the RIV may be decoded in the following manner.

Assuming that P represents the size of the frequency domain resource, O represents the starting position of the frequency domain resource, N represents the number of frequency domain resource units included in the bandwidth of the terminal device, and x represents the RIV value, then it is noted that:

a=floor (x/N) +1, b=x mod N. Wherein floor (·) represents rounding down and mod represents remainder.

Then there is:

if a+b > N, then p=n+2-a, o=n-1-b. Otherwise, p=a, o=b.

In the embodiment of the application, after the terminal equipment determines the starting position and the length of the frequency domain resource occupied by the CORESET, the terminal equipment determines the frequency domain resource occupied by the CORESET.

It will be appreciated that in embodiments of the present application, the frequency domain resources occupied by the CORESET are contiguous frequency domain resource units.

Further, in some embodiments, in response to the presence of a remaining set of resource element REGs that are not mapped to the control channel element CCEs, the remaining REGs are released. The REG which cannot be mapped to the CCE can be released to other terminal equipment or channel for use, so that the resource utilization rate is further improved, and the resource waste is reduced.

In some embodiments, to further save resources and reduce the waste of frequency domain resources, when configuring the size of the frequency domain resources, the network device determines that the product of the size of the frequency domain resources and the number of symbols occupied in the CORESET time domain configured by the network device can be divided by 6, that is, the number of REGs included in the CORESET is an integer multiple of 6.

Note that, because transmission of PDCCH is performed on at least one CCE, one CCE includes 6 REGs. If the product of the size of the frequency domain resource and the number of symbols occupied in the CORESET time domain configured by the network device is not an integer multiple of 6, there may be remaining REGs that cannot be mapped to CCEs, and these remaining REGs may not be used for transmission of PDCCH all the time, resulting in waste of the frequency domain resource. If the product of the size of the frequency domain resource and the number of symbols occupied in the CORESET time domain configured by the network device can be divided by 6, then all REGs included in the CORESET can be mapped to CCEs.

In some implementations, the determination of the size of the frequency domain resources may also take into account an aggregation level. When the aggregation level is higher, the size of the frequency domain resource is matched with the bandwidth supported by the terminal equipment, and the size of the frequency domain resource is as close as possible to the length of the bandwidth supported by the terminal equipment.

In summary, by receiving the indication information sent by the network device, determining the starting position of the frequency domain resource occupied by the control resource set CORESET and the size of the frequency domain resource occupied by the CORESET according to the indication information, the terminal device can support a higher aggregation level as much as possible by changing the allocation mode of the frequency domain resource of the terminal device, effectively improving the transmission performance of the downlink channel, enhancing the coverage of the downlink channel, improving the communication efficiency of the system, effectively reducing the resource waste and improving the resource utilization rate.

Referring to fig. 4, fig. 4 is a flowchart illustrating a frequency domain resource allocation method according to an embodiment of the present application. It should be noted that, the frequency domain resource allocation method in the embodiment of the present application is executed by the terminal device. As shown in fig. 4, the method may include the steps of:

In the embodiment of the present application, the indication information is used to indicate the size of the frequency domain resource.

Step 402, acquiring a starting position of a frequency domain resource occupied by the CORESET specified by a protocol.

In the embodiment of the application, the starting position of the frequency domain resource occupied by the CORESET specified by the protocol can be obtained.

Optionally, the starting position of the frequency domain resource may be a frequency domain resource unit with the lowest frequency of the bandwidth of the terminal device, or may be a frequency domain resource unit with the highest frequency of the bandwidth of the terminal device, or may be a center frequency position of the bandwidth of the terminal device.

Step 403, determining the size of the frequency domain resource occupied by the CORESET according to the indication information.

In the embodiment of the present application, the indication information is used to indicate the size of the frequency domain resource occupied by the CORESET, and the terminal device can determine the size of the frequency domain resource according to the indication information.

Step 404, determining the frequency domain resource occupied by the CORESET according to the starting position of the frequency domain resource occupied by the CORESET and the size of the frequency domain resource.

In the embodiment of the application, after the terminal equipment determines the starting position and the length of the frequency domain resource occupied by the CORESET, the frequency domain resource occupied by the CORESET can be determined according to the starting position and the length of the frequency domain resource.

Referring to fig. 5, fig. 5 is a flowchart illustrating a frequency domain resource allocation method according to an embodiment of the present application. It should be noted that, the frequency domain resource allocation method in the embodiment of the present application is executed by the terminal device. As shown in fig. 5, the method may include the steps of:

step 501, receiving indication information sent by a network device.

In the embodiment of the application, the indication information is used for indicating the highest aggregation level and the number of time domain symbols of the terminal equipment.

Step 502, obtaining a starting position of a frequency domain resource occupied by the CORESET specified by a protocol.

Step 503, determining the size of the frequency domain resource occupied by the CORESET according to the highest aggregation level of the terminal device indicated by the indication information and the number of time domain symbols.

Wherein, the size of the frequency domain resource has a function relation with the highest aggregation level of the terminal equipment and the number of the time domain symbols.

In the embodiment of the application, the size of the frequency domain resource can be determined according to a certain rule according to the highest aggregation level of the terminal equipment and the number of the time domain symbols.

As an example, the size of the frequency domain resource is N, the highest aggregation level AL of the terminal device is a, the number of time domain symbols is s, and the rule may be that N is equal to or greater than a multiplied by 6/s. For example, the highest aggregation level of the terminal device is 4, and the number of time domain symbols is 3, and then the size of the frequency domain resource is at least 8 frequency domain resource units.

In some embodiments, the size of the frequency domain resource occupied by the CORESET can also be determined according to a certain rule according to the highest aggregation level of the terminal device, the number of PDCCH candidate channels supported by the highest aggregation level, and the number of time domain symbols.

The frequency domain resource occupied by the CORESET may also be determined to be that the center frequency allocates floor (N/2) frequency domain resource units downward (to low frequency) and that the center frequency allocates N-floor (N/2) frequency domain resource units upward (to high frequency). Wherein floor (·) represents rounding down.

When the aggregation level is higher, the size of the frequency domain resource is matched with the bandwidth supported by the terminal equipment, and the size of the frequency domain resource is as close as possible to the bandwidth supported by the terminal equipment.

In summary, the starting position of the frequency domain resource occupied by the CORESET specified by the protocol is obtained by receiving the indication information sent by the network device, the size of the frequency domain resource occupied by the CORESET is determined according to the highest aggregation level and the number of time domain symbols of the terminal device indicated by the indication information, and the frequency domain resource occupied by the CORESET is determined according to the starting position of the frequency domain resource occupied by the CORESET and the size of the frequency domain resource.

Referring to fig. 6, fig. 6 is a flowchart illustrating a frequency domain resource allocation method according to an embodiment of the present application. It should be noted that, the frequency domain resource allocation method in the embodiment of the present application is executed by the terminal device. As shown in fig. 5, the method may include the steps of:

step 601, receiving indication information sent by a network device.

In the embodiment of the present application, the frequency domain resource occupied by the CORESET is at least two discontinuous frequency domain resource unit groups, the indication information is used for indicating the position of at least one frequency domain resource unit group in a plurality of frequency domain resource units configured by the network device, the indication information includes at least 1 bit, and each bit of the indication information can indicate whether a corresponding group of frequency domain resource units is the frequency domain resource occupied by the CORESET.

The frequency domain resource units may be resource blocks RB, physical resource blocks PRB, virtual resource blocks VRBs, common resource blocks CRBs, etc.

Step 602, determining a frequency domain resource occupied by a control resource set CORESET according to the indication information, wherein the frequency domain resource occupied by the CORESET is discontinuous at least two frequency domain resource unit groups, and the frequency domain resource unit groups are obtained by dividing a plurality of frequency domain resource units according to one of at least two granularities.

In the embodiment of the application, according to the indication of the indication information, discontinuous at least two frequency domain resource unit groups occupied by the CORESET can be determined. The frequency domain resource unit group is obtained by dividing a plurality of frequency domain resource units according to one of at least two granularities.

It can be understood that the granularity is the number of frequency domain resource units included in one frequency domain resource group, and is also the number of frequency domain resource units corresponding to each bit in the indication information.

As an example, the granularity may alternatively be 2, 3, or 6. That is, one frequency domain resource group of the CORESET may include 2 frequency domain resource units, may include 3 frequency domain resource units, or may include 6 frequency domain resource units. That is, 1 bit in the indication information may indicate the corresponding 2 frequency domain resource units, may indicate the corresponding 3 frequency domain resource units, and may indicate the corresponding 6 frequency domain resource units.

It should be noted that, in the embodiment of the present application, in at least one frequency domain resource group of one CORESET, the number of frequency domain resource units included in each frequency domain resource group is the same.

In the embodiment of the application, the granularity of the frequency domain resource allocation is changed, and the terminal equipment can support higher aggregation level as much as possible by flexibly configuring the allocation granularity of the frequency domain resource.

In some embodiments, the granularity may be determined based on at least one of:

granularity indication information;

the bandwidth supported by the terminal equipment;

the number of bits of the indication information;

the number of time domain symbols configured by the network device.

Alternatively, the allocation granularity of the frequency domain resource of the CORESET may be determined from a granularity set including at least two granularities based on granularity indication information. For example, the granularity set is {2,3,6}, and the terminal device can determine the allocation granularity of the frequency domain resource of the CORESET from the set {2,3,6}, based on the granularity indication information.

Alternatively, the allocation granularity of the frequency domain resource of the CORESET may be determined based on the bandwidth supported by the terminal device and the number of bits of the indication information. Based on the bandwidth supported by the terminal device and the bit number of the indication information, the number of frequency domain resource units used for indication by each bit of the indication information can be determined, and thus the allocation granularity of the frequency domain resources of the CORESET is determined.

It may be understood that, in the embodiment of the present application, the bandwidth supported by the terminal device may be a bandwidth, or may be a partial bandwidth BWP.

Alternatively, the allocation granularity of the frequency domain resource of the CORESET may be determined based on the number of REGs occupied by CCEs and the number of time domain symbols configured by the network device.

Alternatively, the allocation granularity of the frequency domain resource of the CORESET may be determined based on the number of time domain symbols configured by the network device. As an example, for example, based on the number of time domain symbols configured by the network device being 2 or 4, determining that the allocation granularity of the frequency domain resource of the CORESET is 3; and determining that the allocation granularity of the frequency domain resource of the CORESET is 2 based on the number of the time domain symbols configured by the network equipment is 3.

In some embodiments, there is at least one combination of the number of time domain symbols and granularity, and the number of time domain symbols and the corresponding granularity corresponding to the index may be indicated by the index.

In some embodiments, when the aggregation level is higher, the frequency domain resource of the CORESET matches the bandwidth supported by the terminal device, and the size of the frequency domain resource is as close as possible to the bandwidth supported by the terminal device.

In summary, by receiving indication information sent by a network device, determining frequency domain resources occupied by a control resource set CORESET according to the indication information, where the frequency domain resources occupied by the CORESET are at least two discontinuous frequency domain resource unit groups, and the frequency domain resource unit groups are obtained by dividing a plurality of frequency domain resource units according to one of at least two granularities, and by flexibly configuring allocation granularities of the frequency domain resources, a terminal device can support a higher aggregation level as much as possible, effectively improve transmission performance of a downlink channel, enhance coverage of the downlink channel, improve system communication efficiency, effectively reduce resource waste, and improve resource utilization rate.

It should be noted that, because the resource allocation manner of coreset#0 is different from other CORESETs, in embodiments of the present application, if the CORESET is coreset#0, the indication information is the remaining minimum system message RMSI (Remaining Minimum System Information), and the RMSI signaling is used to determine the frequency domain resource length and the corresponding symbol number of coreset#0 from the combination of at least one frequency domain resource length and the corresponding symbol number agreed by the protocol.

As an example, when the subcarrier spacing SCS is 30KHz, the combination of at least one frequency domain resource length and the corresponding symbol number agreed by the protocol may be as shown in the following table.

Table 1 frequency domain resource length of coreset #0 and corresponding symbol number configuration

In order to improve the resource utilization rate, reduce unnecessary resource waste, and improve the transmission efficiency and quality, when designing the combination of the frequency domain resource length of coreset#0 and the corresponding symbol number, the frequency domain resource length may be satisfied as far as possible without exceeding the bandwidth supported by the terminal device, where the number of REGs (that is, the product of the number of RBs and the symbol number) included in the combination of the frequency domain resource length and the corresponding symbol number is an integer multiple of 6 as far as possible, and so on.

It will be appreciated that this table is given by way of example only, and that some possible combinations of frequency domain resource lengths and corresponding symbol numbers for CORESET #0 are exemplary, and that many more combinations may be devised to meet and accommodate many more scenarios and bandwidth requirements, and is merely exemplary and not limiting of embodiments of the present application.

The terminal equipment can determine the frequency domain resources occupied by CORESET according to the indication information.

Wherein, optionally, the size of the frequency domain resource may be matched with the bandwidth supported by the terminal device, so as to avoid resource waste.

In some embodiments, the granularity is determined based on at least one of: granularity indication information; the bandwidth supported by the terminal equipment; the number of bits of the indication information; the number of resource element groups REG occupied by a control channel element CCE; the number of the time domain symbols configured by the network equipment can flexibly configure the allocation granularity according to actual conditions, so that the resource utilization rate is further improved, and the resource waste is avoided.

In the embodiment of the present application, if the control resource set CORESET is coreset#0, the first indication information is a remaining minimum system message RMSI, and the RMSI signaling is used to determine the frequency domain resource length and the corresponding symbol number of coreset#0 from a combination of at least one frequency domain resource length and the corresponding symbol number agreed by a protocol.
